Attio to Nimble integration — real-time, two-way sync

Yes. Stacksync provides a managed, real-time two-way integration between Attio and Nimble: authenticate both systems, choose the objects to sync (such as Attio's Deals and Workspaces), map fields visually, and changes propagate both ways in milliseconds — no code required.

Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.

Common patterns for Attio and Nimble: Divisional or regional split; Where both track pipeline: deal visibility across systems; Post-acquisition consolidation. Where each CRM serves a different team or region, sync just the shared accounts and contacts so handoffs and cross-sell work.

Attio: REST API. Authentication: Guided in-app connection ("Attio CRM" connection created in a few clicks, "without any coding required"); the docs do not name the underlying auth mechanism (OAuth vs API key). Nimble: REST API (JSON). Authentication: API key; OAuth 2.0 available for registered applications. Stacksync manages authentication, retries, and rate limits on both sides.

Attio: The data model is user-definable: standard objects like people and companies coexist with custom objects, and attributes can be added to any object, so syncs read the schema at runtime. Nimble: Nimble stores people and companies as contact records distinguished by record type, so both entity types flow through the same contacts resource. Stacksync's field mapping accounts for these differences between Attio and Nimble without custom code.

Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Attio and Nimble records are not retained after a sync operation.
